Description

Technical Field

[0001] The invention relates to the technical field of tension clamps, in particular to a tension clamp device for a high-voltage transmission line. Background Art

[0002] The conductor tension clamps in the transmission line usually adopt a crimping structure, which crimps the steel anchor of the tension clamp to the steel core of the conductor and the aluminum tube of the tension clamp to the aluminum wire of the conductor, respectively, and uses the friction generated by the crimping between the conductor and the tension clamp to achieve the grip of the conductor by the tension clamp. However, the hydraulic tension clamp is not only inconvenient to install on site, but also requires the conductor to be disconnected and wired before installation. In addition, leakage and undervoltage often occur during the crimping process of the tension clamp, which has a certain impact on the smooth operation of the transmission line. The Chinese patent announcement number is: CN118431986B, which discloses "A fast double-braking self-locking tension clamp". In this patent, reversing support is achieved through the conductor body. At this time, the elastic potential energy of the quick locking mechanism is released so that the conductor body is clamped near the guide assembly. The iron ball on the inner side of the wire rope effectively increases the friction resistance of the wire rope. Both ends of the conductor body near the guide assembly are clamped by the quick locking mechanism, and the guide assembly is subjected to dispersed force, which solves the problem that the reversing conductor exerts too much tension on the tension clamp, which easily causes the clamp to fall off. However, when in use, the cable is not pulled on one side, and this clamping method will make the cable unable to be firmly clamped.

[0003] The existing tension clamp device for high-voltage transmission lines has problems in how to quickly erect and install the bidirectionally pulled switching conductors due to structural design defects, and the frequent bending of the suspension cable during the shaking process in windy weather will cause it to wear out quickly.

[0017] The present invention provides a tension clamp device for a high-voltage transmission line, which has the following beneficial effects: 1.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] First embodiment: Figure 1-Figure 4 As shown, the present invention provides a technical solution: a tension clamp device for a high-voltage transmission line, comprising a fixing frame 1, a surface of which is fixedly connected with a fastening bolt 2, and further comprising: The reeling and unwinding mechanism 3 is fixedly mounted at the middle position of the inner side surface of the fixed frame 1, and a cable 4 is sleeved and fixed at the middle position of the surface of the reeling and unwinding mechanism 3, and the end surface of the cable 4 is wound along the axial direction of the reeling and unwinding mechanism 3; A first wire clamping mechanism 5, the first wire clamping mechanism 5 is rotatably mounted on the surface of the reeling and unwinding mechanism 3, and the first wire clamping mechanism 5 is used for clamping and limiting the unwinding position of the cable 4 and supporting and guiding the cable 4 to be deflected by tension; A second wire clamping mechanism 6, which is arranged opposite to the first wire clamping mechanism 5, and is rotatably connected to the first wire clamping mechanism 5; The drag reduction mechanism 7 is fixedly mounted on a side of the first clamping mechanism 5 away from the reeling and unreeling mechanism 3.

The top and bottom of the slotted shaft 31 are both provided with slots.

[0026] When in use, when the reversing cable is installed, both ends of the cable are pulled to the fixed point by force. In the prior art, the cable 4 is passed through the reversing device by pulling only one end. The excessive pressure between the cable 4 and the reversing device can easily cause pressure damage to the cable 4. In the device, the middle position of the surface of the cable 4 is limited by the limiting component 36, and the cable 4 is wound on the rotating roller 34. The two ends of the cable 4 pass through the first clamping mechanism 5 and the second clamping mechanism 6 respectively, driving the component 35 to drive the slotted shaft 31 to rotate. When the slotted shaft 31 rotates, it drives the rotating roller 34 to rotate. When the rotating roller 34 rotates, the cable 4 is unwound. At the same time, external force drives the cable 4 to be pulled to the fixed point. When the pulling force is removed, the first clamping mechanism 5 and the second clamping mechanism 6 clamp the surface of the cable 4, so that the surface of the cable 4 has a large tension and is not easy to fall, thereby realizing the rapid clamping of the reversing cable, solving the problem of how to quickly erect and install the reversing conductor that is subjected to bidirectional force.

[0027] Second embodiment: Figure 3-Figure 6 As shown, the driving component 35 includes a limit plate 351, which is fixedly installed on the top of the fixed frame 1, and the top of the limit plate 351 is fixedly connected to an electric turntable 352, and the output end of the electric turntable 352 is fixedly connected to an inner groove cylinder 353, and the driving component 35 also includes a guide slide 354, the inner side surface of the guide slide 354 is fixedly installed at a position above the surface of the electric turntable 352, and the surface of the guide slide 354 is fixedly connected to a fixed body 356, and the inner side surface of the fixed body 356 is fixedly connected to a guide slide rod 355; The limiting assembly 36 includes a pulling plate 361, which is fixedly installed in the middle position of the surface of the fixed frame 1, and the inner side of the pulling plate 361 is fixedly connected to the support ring 362. The limiting assembly 36 also includes an extension platform 363, which is fixedly installed on the surface of the support ring 362 near the edge, and the inner side of the extension platform 363 is fixedly connected to the rubber tube 364.

[0028] When in use, the extension platform 363 supports the middle position of the cable 4, and then the rubber tube 364 is inserted into the inner side of the extension platform 363 so that the cable 4 is blocked by interference fit. The fixed support of the pulling plate 361 and the support ring 362 restricts the rotation of the middle position of the cable 4. The two ends of the cable 4 are respectively wound upward and downward on the surface of the rotating roller 34. The surface of the rotating roller 34 is provided with a threaded groove, which makes it difficult for the cable 4 to slip when it is wound. The inner groove cylinder 353 is engaged with the slotted position of the slotted shaft 31. When the cable 4 is in the unwinding state, the two ends of the cable 4 are passed through the first clamping mechanism 5 and the second clamping mechanism 6. The clamping mechanism can limit the cable 4. When the electric turntable 352 drives the inner groove drum 353 and the slotted shaft 31 to rotate, the rotating roller 34 causes the two ends of the cable 4 to be unwound at the same time. The two ends of the cable 4 are pulled to the fixed point for fixing. When the cable needs to be recovered, the fixed point releases the cable, and the rotating roller 34 rotates to recover the cable, so that the pressure of the cable 4 and the reversing position is small and not easily damaged.

[0029] The third embodiment: Figure 3 , Figure 7 As shown, the slotted shaft 31 is slidably mounted on the inner side of the fixed frame 1, a rotating roller 34 is fixedly connected to the surface of the slotted shaft 31, a driving component 35 is slidably connected to the top of the slotted shaft 31, an output end of the driving component 35 is in close contact with the surface of the slotted shaft 31, and a limiting component 36 is fixedly connected to the middle position of the surface of the fixed frame 1; A pressing plate 32 is sleeved on the surface of the slotted shaft 31, and a pressing bolt 33 is connected to the position between the pressing plate 32 and the fixed frame 1. The top and bottom of the slotted shaft 31 are both provided with slots. The first wire clamping mechanism 5 includes a U-shaped plate 51, and the end face of the U-shaped plate 51 is rotatably mounted on the outer surface of the slotted shaft 31. A bent rod 52 is fixedly connected to the surface of the U-shaped plate 51, and a fixed platform 53 is fixedly connected to the surface of the U-shaped plate 51. The first wire clamping mechanism 5 also includes an inner spherical shell 54, which is fixedly mounted on the end face position of the fixed platform 53, and a pressing sleeve 55 is fixedly connected to the surface of the inner spherical shell 54. The inner side surface of the inner spherical shell 54 is sleeved with a clamping assembly 56.

[0030] When in use, the limiting component 36 fixes the middle position of the surface of the cable 4. When installed, the U-shaped plate 51 slides to the top of the pressing plate 32. The first wire clamping mechanism 5 and the second wire clamping mechanism 6 have the same structure. The inner side surfaces of the first wire clamping mechanism 5 and the second wire clamping mechanism 6 are both sleeved on the surface of the slotted shaft 31. The fixing platform 53 fixes the clamping component 56 and the U-shaped plate 51, and the slotted shaft 31 is fixed through the rotating roller 34 and the U-shaped plate 51 in sequence. The end surface of the cable 4 is pulled by external force through the inner side surface of the clamping component 56. Under the tension of the cable 4, the first wire clamping mechanism 5 and the second wire clamping mechanism 6 rotate to form a certain angle. When the external force is removed, the clamping component 56 firmly clamps the surface of the cable 4. At the same time, the rotating roller 34 retracts and limits the middle position of the surface of the cable 4, so that the cable 4 has a large tension and is not easy to shake, which solves the problem that the frequent bending of the suspended cable during shaking in windy weather will cause it to wear quickly.

[0031] Fourth embodiment: Figure 7 , Figure 8 , Fig. 9 As shown, the clamping assembly 56 includes a clamping shell 561, which is fixedly mounted on the inner side of the inner spherical shell 54, and a shrinking tube 562 is connected to the surface of the clamping shell 561 through a thread, and a hydraulic cylinder 563 is fixedly connected to the surface of the shrinking tube 562 away from the clamping shell 561. The clamping assembly 56 also includes a driving plate 564, which is fixedly mounted on the output end of the hydraulic cylinder 563, and a spring 565 is fixedly connected to the surface of the driving plate 564, and a clamping block 566 is slidably connected to the inner side of the shrinking tube 562; The drag reduction mechanism 7 includes a support shell 71, which is fixedly mounted on the outer surface of the U-shaped plate 51. The inner side surface of the support shell 71 is rotatably connected to a perforated ball 72, and a through hole is formed on the inner side surface of the perforated ball 72. The drag reduction mechanism 7 also includes a conical shell 73, the surface of the conical shell 73 is in close contact with the inner side surface of the perforated ball 72, and a pin 74 is fixedly connected to the inner side surface of the conical shell 73. The positions between the conical shells 73 are connected by threaded connection bolts 75.

[0032] When in use, the inner spherical shell 54 and the pressing sleeve 55 cooperate to press and fix, so that the clamping shell 561 and the U-shaped plate 51 are firmly connected, so that the cable 4 is more stable when being pulled and fixed, and the cable 4 passes through the inner side of the four clamping blocks 566, and the four clamping blocks 566 are pushed to make the driving plate 564 close to the compression spring 565. At this time, there is no hydraulic pressure inside the hydraulic cylinder 563, and the spring 565 is compressed. The cable 4 passes through the clamping shell 561 and the perforated ball 72, and the support shell 71 supports the perforated ball 72 for rotation. After the end face of the cable 4 is fixed, the spring 565 releases its elastic potential energy to cause the clamping block 566 to move in the opposite direction. The conical structure formed by the four clamping blocks 566 is limited by the shrinking tube 562. The inner side of the clamping block 566 quickly clamps the surface of the cable 4. When the cable 4 needs to be reeled in, hydraulic pressure is passed into the interior of the hydraulic cylinder 563. The hydraulic pressure compresses the spring 565, and the cable 4 is quickly released. The rotating roller 34 rotates to reel in the cable 4, thereby realizing the rapid and stable disassembly and assembly of the reversing cable 4.

[0033] Fifth embodiment: Figure 5 , Fig. 9 As shown, the limit plate 351 is fixedly installed on the top of the fixed frame 1, the top of the limit plate 351 is fixedly connected to the electric turntable 352, the output end of the electric turntable 352 is fixedly connected to the inner groove cylinder 353, the driving component 35 also includes a guide slide 354, the inner side surface of the guide slide 354 is fixedly installed on the upper position of the surface of the electric turntable 352, the surface of the guide slide 354 is fixedly connected to the fixed body 356, and the inner side surface of the fixed body 356 is fixedly connected to the guide slide rod 355; The support shell 71 is fixedly mounted on the outer surface of the U-shaped plate 51, and the inner side surface of the support shell 71 is rotatably connected to the perforated ball 72, and the inner side surface of the perforated ball 72 is provided with a through hole. The drag reduction mechanism 7 also includes a conical shell 73, and the surface of the conical shell 73 is in close contact with the inner side surface of the perforated ball 72. The inner side surface of the conical shell 73 is fixedly connected to a pin 74, and the position between the conical shells 73 is connected by a connecting bolt 75 through a thread.

[0034] When in use, the electric turntable 352 is used to control the rotation of the rotating roller 34. The rotating roller 34 causes the cable 4 to be wound near the middle of the surface, so that the cable 4 has a large tension inside and is not easy to fall and shake. The clamping block 566 and other structures are placed inside the shrinking tube 562. The clamping block 566 is provided with a convex surface inside. The inner side surface of the shrinking tube 562 and the outer surface of the clamping shell 561 are quickly connected by threads. The cable 4 passes through the inner side surface of the perforated ball 72, and the perforated ball 72 provides sliding support for the cable 4. After the end face of the cable 4 is fixed, two oppositely arranged conical shells 73 are sleeved on the surface of the cable 4. After the conical shells 73 are connected by the pins 74, the conical shells 73 are pushed to the gap between the perforated ball 72 and the cable 4. The conical shell 73 made of rubber material allows the perforated ball 72 and the cable 4 to be quickly fixed. Then, the connecting bolts 75 are used to prevent the conical shell 73 from being easily separated. When the cable 4 is pushed by external force, the perforated ball 72 rotates on the inner side of the supporting shell 71, so that the cable 4 has a better wear resistance.
